To aZZ whom it may concern.-

Be it known that we, LUTHER V. MOULTON and HOMER L. BOYLE, citizens of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Vending Apparatus for Liquids; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to vending apparatus for liquids; and the obj ect of our invention is to produce a simple durable device having a suitable tank for containing the liquidto be vended and provided with mechanism whereby a measure of the liquid can be drawn from the tank by introducing a coin through a suitable opening into the mechanism of the apparatus, and that cannot be operated. except by the introduction of such coin or some equivalent article of substantially the same size, weight, and form; and the invention consists in the peculiar construction, combination, and arrangement of the various parts, as hereinafter more fully described, and pointed out in the claims, reference being had to the accompanying drawings, wherein-e Figure 1 is a front elevation of adevice embodying our invention; Fig. 2, a vertical section on the line 00 m of Fig. 1, and Fig. 3 a horizontal section on the line y 1/ of Fig. 2.

Like letters and figures of reference indicate like parts in each of the several figures.

A represents any suitable tank for containing the liquid to be vended, and is provided with a false bottom 0, and may also be provided with an inner receptacle B for containing ice to cool said liquid.

D is a case inclosing the vending mechanism, having a chamber between the falsebottom 7 and the diaphragm 6 to protect said mechanism from injury.

E is a coin-chute consisting of a serpentine tube communicating with a slot E and provided with vent-openings IV to prevent the device from being operated by air blown into the slot E.

F is a measure which rests and is adjusted to fit closely upon the platform G and has a closed bottom provided with a single opening or port H, which registers with a correspond ing port or opening H in the platform G for admitting the liquid to the measure, and another port II for discharging its contents into the vessel J by means of spout I communicating with port H, and has a heavy cover 3 to holdit upon its seat on the platform when the tank is filled with aliquid, and vent-pipes 1 and 2 (2 being flexible for permitting alongitudinal movement of F) for permitting the escape of air.

K is a pull-rod, which passes through the casing D, and is provided with a knob 3 and a spring S, having an adjusting-nut 5, and a tight gland M, having a suitable packing to prevent the liquid from following the rod out of the tank. The rod K is attached to F by a loose joint L, and has a notch 4, into which takes the pawl N of the lever O, which is pivoted to the post R, resting upon false bottom 7. One end of the lever O is flattened and adapted to close the bottom of the coin-chute E. The other end passes through the loopstop Q, (which is secured to and moves with the rod K,) and is provided with adjustable weight P. In the chamber underneath the false bottom of D is arranged a cash-box U, which communicates with the coin-chute E by the opening T through the false bottom 7.

V is a drip-pipe communicating with the floor of the chamber containing the vessel J.

The apparatus operates substantially as follows: Liquid placed in the tank flows through the port II into the measure F, the air escaping through the pipes 1 and 2. A coin introduced through the slot E, passing down the slot E, lodges upon theouter end of the lever O, depressing it sufficiently to disengage the pawl N from the notch 4; but the opposite end of the lever is engaged at the same time by the loop-stop Q and prevents it from being depressed low enough to permit the coin to fall off the outer end until the rod K is drawn out. When this is done, the stop Q, moving with the rod, permits the weighted end of the lever to rise, and the other end being at the same time depressed by the weight of the coin, the coin is disengaged from the sides of the chute and falls 0K through the opening T into the cash-box U. At the same time the measure F is drawn I on said measure for permitting the escape of explained. The rod K being released, the

spring S causes it to resume its former position, pushing the measure F along upon its seat upon the platform until the ports II and H" again register. The weight P causes the lever O to resume its former position, the pawl- N re-engages the notch 4, the measure refills, and the operation may be repeated indefinitely.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is

1. In a vending apparatus for liquids, the combination, with a suitable tank, of a platform arranged inside of said tank adapted to support a measure, said platform having a port communicating with the interior of said tank, and another port communicating with a discharge-pipe, a measure resting on said platform and adapted to slide thereon, said measure having a closed top, and a bottom having a port adapted to communicate alternately with said platform-ports, a vent-pipe air, and a rod for sliding said measure, arranged substantially as described, and for the purposes set forth.

2. In a vending apparatus for liquids, the combination, with a suitable tank provided with a false bottom, of a platform supported upon said bottom and provided with a port communicating with the interior of said tank, and another port communicating with a discharge-pipe, a measure resting on said platform and adapted to slide thereon, said measure having a closed top, and a bottom having a port adapted to register alternately with the ports in said platform, and a flexible ventpipe for permitting the escape of air.

3. In a vending apparatus for liquids, the combination, with a suitable tank for containing the liquids and a casing for inclosing the operating mechanism, of a coin-chute arranged within and communicating with the exterior of said casing, a pivoted lever having an arm adapted to close the bottom of said coin-chute and provided with a weight at its other end, and a pawl arranged near the pivot, a pull-rod having a notch adapted to engage said pawl, and a measure arranged within said tank, said measure being adapted to slide horizontally connected to said pullrod, arranged substantially as described, and for. the purposes set forth.

4. In vending apparatus for liquids, the combination, with a suitable tank for containing the liquid, of a coin-chute connected to said tank, a pivoted lever having a flattened surface at one end adapted to close the bottom of the chute and provided with an adjustable weight at the other end, and a pawl arranged near the middle, a pull-rod provided with a notch adapted to engage with said pawl, a stop secured to said rod and adapted to engage the weighted end of said lever, and a horizontally-movable measure attached to said pull-rod, arranged substantially as described, and for the purposes herein set forth.
